146 BALFOUR—NEwW SPECIES OF RHODODENDRON. 
which is detersile and may leave the petiole glabrous. Flowers 
in a terminal about 10-flowered umbel the rhachis hardly elon- 
gated ; outer bracts rounded truncate mucronulate more or less 
puberulous outside, inner bracts oblong-spathulate 3.5 cm. long 
I cm. or more broad apiculate silky ; bracteoles about 1.5 cm. 
long filiform with long wavy hairs from the base and at the top 
densely clothed with straight erect hairs forming a hair-crest ; 
pedicels under 2 cm. long green glandular with short-stalked 
globose glands, not swollen below calyx. Calyx small about 
i mm. long green or pink showing 5 half-moon-shaped lobes 
glabrous or with an occasional gland. Corolla as much as 5. 
cm. long funnel-shaped campanulate from the base pink often 
showing deeper tinted interpetaline lines glabrous inside and 
outside somewhat fleshy, at base of tube gibbous and retuse ; 
limb expanding into 7 erect emarginate rounded lobes as much 
as 1.2 cm. long 2.4 cm. broad. Stamens 14 unequal much 
shorter than corolla and gynaeceum, longest about 3 cm. long 
with anther 2.5 mm. long, shortest about 1.7 cm. long with 
anther 1.5 mm.; filaments widened downwards puberulous 
towards base; anthers black-crimson. Disk green glabrous. 
Gynaeceum a little shorter than corolla; ovary broad dome- 
shaped with rounded top not conspicuously grooved most 
glabrous about 5 mm. long; style glabrous pink-tinted slightly 
swollen below the broad discoid lobulate stigma. 
Szechwan. Wilson. 
Mr. J. C. Williams gives me the following history of this plant, 
of which he has sent to me a specimen from Caerhays :—“‘ It 
was a rogue which I found at Coombe Wood in a bed with the 
label 1882. Harrow was quite certain it had no relationship 
to any of his hybrids. I remember turning to them and going 
over the bed to see if I could find anything like it and I was 
unable to. I am unable to find anything like it here. As to 
what 1882 was as regards the other plants I am unable to re- 
member and only know that it seemed plain to me there was 
no relationship direct or indirect between them. I have never 
let this plant get out of touch with me since it came here.”’ Mr. 
Williams gives the following copy of Wilson’s Field Note :— 
“1882. Rhododendron. Bush 4-12 ft. Rose. Mts. Tatsienlu. 
Leaves ovate-cordate’’; and adds the note, ‘‘in this case is not 
in his handwriting.”’ 1882 isnot attached in Plantae Wilsonianae 
to a Rhododendron. It is clear that the label copied by Mr. 
Williams does not apply to Rh. planetum—the description of the 
leaves of 1882 as ‘“‘ ovate-cordate”’ indicates a different plant. 
I cannot match what Iam calling Rh. planetum with any known 
species. The look of the foliage and flower-truss and flower 
suggests the Decorum series. It has the long leaves of RA.
